Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711382, here are decompositions:

5 + 8711377 = 8711382
19 + 8711363 = 8711382
23 + 8711359 = 8711382
193 + 8711189 = 8711382
223 + 8711159 = 8711382
241 + 8711141 = 8711382
311 + 8711071 = 8711382
331 + 8711051 = 8711382

Showing the first eight; more decompositions exist.
